Comparing sourcing strategies in two-echelon supply chains
In this paper we investigate four sourcing models with respect to both cooperative or noncooperative planning strategies, and sole or dual sourcing. A two-stage supply chain is considered, which includes a single buyer and either a single or dual vendor(s). At the buyer the product is consumed at a constant rate, and an (r, Q) policy is used to generate replenishment orders. The vendors have a ...
متن کاملResponsible Sourcing in Supply Chains
We analyze the sourcing decision of a buyer choosing between two supplier types: responsible suppliers are costly but adhere to strict social and environmental responsibility standards, while risky suppliers are less expensive but may experience responsibility violations. A segment of the consumer population, called socially conscious, is willing to pay a higher price for a product sourced from...
متن کاملInventory Resonances in Multi-echelon Supply Chains
We consider multi-echelon supply chains, typically consisting of retailer, distributor, manufacturer, etc. The inventory of each actor is subject to its own delay in delivery time, and each chooses its own inventory replenishment strategy. We model this interaction with a system of linear differential delay equations. When put in matrix form the system is triangular and we derive an exact solut...
متن کاملSupplement to “ Responsible Sourcing in Supply Chains ”
In this section, we allow consumers’ base valuations for the product to be uniformly distributed on the interval [vl, vh], independent of consumer type (socially conscious or non-socially conscious), where V = vh vl is defined as the width of the consumer valuation distribution. Socially conscious consumers are assumed to have homogenous, additive willingness-to-pay for responsibility equal to ...
متن کاملSupply and Demand Uncertainty in Multi-Echelon Supply Chains
This paper explores the differences between demand and supply uncertainty in multi-echelon supply chains. Our central premise is that the insights gained from the study of one type of uncertainty often do not apply to the other. In fact, the two types of uncertainty are in a sense mirror images of each other, in that the optimal strategy for coping with supply uncertainty may be exactly opposit...
